2" & 3" tank lifts effect on gas gauge?

I recently swapped out the tank and I put a half gallon of gas in, then adjusted the gauge sending unit arm to trigger the warning light right at the half gallon level. The sending unit float is pretty much sitting on the bottom of the tank at a half gallon. I still rely on the odometer but it is nice to have the gauge functioning, and now when my warning light comes on I know I have a half gallon left (about 20 miles).

First of all one of the reasons I bought my FXD was because I liked the look of the tank - it's just a cleaner look. I have a 2" lift and haven't had the bad experiences other guys here have dealt with. I ran out of gas once and now appreciate the fact that my low fuel light comes one with a gallon or so of gas left in the tank. And, after my long *** walk I also use the odo method. If you've ever walked 2-3 miles in Louisiana in August you'll understand.

Thanks for the replies everyone, was basically what I was expecting.
WS6, do you have a writeup, or a how to to "tweak" your gas gauge to work better with a tank lift? This sounds really interesting.
Thanks bro.

Gauge will read lower then actual after tank lift. I raised my tank 1.60", warning light came on earlier. I recently swapped out the tank and I put a half gallon of gas in, then adjusted the gauge sending unit arm to trigger the warning light right at the half gallon level.

Please tell me you took pictures of this and want to post them here. I am going to swap my tank in the next few weeks and wanted to poke around in there to see if I could do that exact thing. My 3" lift threw off the gauge, even though I use the trip meter. But I like to have my shat working properly...
I don't have a write up, but basically you remove your console and tank access plate, remove the sending unit. The float rod has a "V" bend right by the sending unit, use two pliers to open up that angle of that "V" just a little, put the sending unit back in and with you sitting on the bike upright, turn on your ignition and run switch and wait a few minutes because the signal to the gage is delayed. You will have to do this several times until you get the reading you want. Like I mentioned in my previous post, I used a half gallon of fuel and set that point to trigger my low fuel warning light.

I'm kicking around the idea of doing a 2" or 3" tank lift on my fxdb but was wondering how much it would throw off the accuracy of the gauge. I already know the gauge isn't as reliable as it should, but it is somewhat close to reliable to when I need gas & such.
Just am afraid if I put on a 3" lift my gauge will be showing half full and the tank will be empty.
Any thoughts on gauge accuracy after a tank lift had been installed.

All us poor suckers are riding around with no idea how much fuel we have.
This sounds like a quick easy fix.
